the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same. v

This invention relates to a motor drive for shapers or other woodWorking machines of similar character and it is the object and purposeof. the present invention to provide a motor and connect it directly bygearing to the spindle of the shaper which carries the cutters thereof.A further object of the invention is to connect themotor withthe spindlein such manner that an adjustment of the spindle by movement of thesupport on which it is mounted carries with it the motor carried by thesame support, there being, in this manner, provided a motor drive forwood working shapers, the driving means and the cutter for the shaperbeing simultaneously adjustable without the ne--' cessity of independentadjustment of each.

In the drawings is shown a practical and operative construction wh1chembodies my invention and in which,

' Figure 1 is a perspective view of a shaper equipped with my invention.

Fig. 2 is a similar view from the opposite side.

Fig.3 is a plan viewof the cutter head. Fig.4 is a side elevation withbearings shown in section to illustrate the mounting of the spindle ofthe shaper and v Fig. 5 is a detail in section illustrating theconstruction for adjusting the cutters and partsassociated therewithwith respect to a stationary table which forms one part of the shaperconstruction.

Like reference characters ,refer' to like parts in the several views ofthe drawings. In the construction of the shaper a heavy support 1,preferably of cast iron, is made which carries an upper horizontal table2 on which the work acted upon by the shaper is laid. A. verticalspindle 3 is mounted in suitable lower and upper thrust and ballbearings 4 and 5, said spindle extending through the table and carryingat its upper end a cutter head 6 on which suitable knives may besecured. The upper end of the Specification of Iietters Patent.

] Pe s e n el 9 8-1 Application filed May 10, 1917. Serial No. 167.734.

spindle rotatably mounted a bearing- 7 supported at the upper end ofandextending laterally froma post 8' which also extends upwardly throughthe table 2. Lower and upper brackets 9 and 10 project laterally fromthe support for the spindle 3 between which an electric motor 11 ispositioned. The shaft of the motor is vertical and suitably mounted atits upper and lower ends in bearings in said brackets 10 and 9 similarto the bearings used, as shown in Fig. 4

for the spindle 3 of the machine. A spur gear 12 is connected to themotor shaft nieshing with pinion 13 fixed on the spind e 3.

In practice it is desirable that the cutter maybe vertically adjustablewith respect to the table. Accordingly, the spindle 3 and the brackets 9and 10, as well as the post 8 are connected to a support 14: slidablymounted between guides 15 on the main casting or base 1. An arm 16projectsfrom the lower bracket 9 through which is threaded a screw 17theu per end-thereof passing into a housing 18 liked on the main casting1 and carrying a beveled pinion 19 at its upper endwithin the housing. A

. second beveled pinion 20 meshes with pinion 19 being fixed on theinner end of a shaft,

21 which extends outwardly through the housing and carries an operatinghand wheel I 22 at its outer end. It is apparent that rotation of thehand wheel moves'the. support carrying the spindle and the motor andthat all may be adjusted simultaneously. Of"

course, more than one cutter head. and spindle may be mounted on asingle base as 1 indicated in Fig. 2, but'the construction andadjustment is the same whether one or more cutters are used witha singletable.

Theconstruction described is very eflicient in practice and does away.with the 1 complicated beltdrive heretofore considered essential withshapers driven at a' very high speed .at' which wood working machinerymust run. The balland thrust .bearings for the cutter spindle and forthe motor shaft render the same very easy of operationand' theconnection of the motor direct to the a simultaneousmovement ofrbothwithout the necessity ofindependent adjustments for each. 7

I'claim: I In a machine of the character described, a supporting base, ahorizontal table carried support which carries the spindle permits.

the table and rotatively mountedv on supporting member, a cutter headcarried by the upper portion of the spindle, upper and lower bracketsfi'xedon the supporting member and projecting laterally therefrom, amotor located between the brackets, the

ends of the motor shaft having bearings in 10 the brackets a gear on themotor shaft, a

"pinion on the'spin'd'lemeshing with the gear,

andrmeans for raising or lowering said supporting member and attachedspmdle and nlotor relative to said base table,f-sub- 15 stantially asdescribed.

In testimony whereof I aflix my signature;
